Hello,
how can I best fill a (fixed) matrix with vectors of varying lengths by
column, setting the superfluous elements to zero? Here is my code:
v<-(1,1,2,3,4,6)
binc<-function(x){
l<-sum(x)+1
y<-c(1,rep(0,l-1))
for (i in x) y<-y+c(rep(0,i),y)[1:l]
}
mat<-matrix(0, nrow=sum(v)+1, ncol=length(v))
for (i in 1:length(v)) mat[,i]=mat[,i]+binc(v[1:i])
the expression in the for-loop produces an error since mat[,i] and
binc(v[1:i]) are of unequal lengths, except on the last iteration.
Thanks in advance,
Serguei
